Image forming apparatus, method for controlling the image forming apparatus, and program, with mode shifting based on duration required for shifting and amount of information to be stored

摘要

An image forming apparatus includes a first volatile storage unit storing information for returning the image forming apparatus to a normal startup state, a second non-volatile storage unit storing the information for returning the image forming apparatus to the normal startup state, and a control unit configured to, if the image forming apparatus being performing normal job processing is shifted to the power-saving mode, switch between a hibernation mode and a quick mode depending on a shift time to the hibernation mode, the hibernation mode in which the control unit causes the second storage unit to store information for performing the normal job processing to shift the image forming apparatus to the power-saving mode, the quick mode in which the control unit causes the first storage unit to store the information for performing the normal job processing to shift the image forming apparatus to the power-saving mode.

1. An image forming apparatus comprising:
a first volatile storage unit configured to store information for returning the image forming apparatus to a normal startup state; a second non-volatile storage unit configured to store the information for returning the image forming apparatus to the normal startup state; and a control unit configured to, when the image forming apparatus is shifted to a power-saving mode, shift the image forming apparatus to a hibernation mode in a case where duration required for shifting the image forming apparatus to the hibernation mode is within a predetermined time period and shift the image forming apparatus to a quick mode in a case where the duration required for shifting the image forming apparatus to the hibernation mode is not within the predetermined time period, the hibernation mode in which the control unit causes the second non-volatile storage unit to store therein the information for returning the image forming apparatus to the normal startup state, the quick mode in which the control unit causes the first volatile storage unit to store therein the information for returning the image forming apparatus to the normal startup state wherein the control unit is configured to, when the image forming apparatus is shifted to the power-saving mode, shift the image forming apparatus to the quick mode in a case where the information that is to be stored in the second non-volatile storage unit is stored in memory blocks, a number of which exceeds a predetermined number in the first volatile storage unit.
